  • RuO-coated fibrous insulator
    Patent number: 8889257
    Abstract: An article having: a nonconductive fiber and a RuO2 coating. A method of: immersing a nonconductive article in a solution of RuO4 and a nonpolar solvent at a temperature that is below the temperature at which RuO4 decomposes to RuO2 in the nonpolar solvent in the presence of the article; and warming the article and solution to ambient temperature under ambient conditions to cause the formation of a RuO2 coating on a portion of the article. An article having: a nonconductive fiber and a coating. The coating is made by electroless deposition, sputtering, atomic-layer deposition, chemical vapor deposition, or physical vapor deposition.
